Legislation introduced Thursday by two Democratic state senators and nine Democrats in the Assembly would require issue advocacy organizations such as Reform Jersey Now, the new Republican group airing ads in support of Gov. Chris Christie’s agenda, to disclose contribution and expenditure information.

The proposal [1]is sponsored in the Senate by Sen. Nicholas Scutari and Sen. Loretta Weinberg, who was the Democratic nominee for lieutenant governor last year. In the Assembly — which will consider the bill Monday in the Judiciary Committee — the nine sponsors include Linda Greenstein, Wayne DeAngelo, Annette Quijano, Ralph Caputo and Paul Moriarty as primary sponsors.

A summary of the bill calls organizations that operate under federal IRS rules, rather than federal or state campaign regulators “‘stealth PACs’ because they are often formed by wealthy individuals or trade groups in an effort to influence the outcome of elections while masking their funding sources.”

Such committees aren’t uncommon. They are not bound by state campaign finance rules, meaning they can accept contributions of any size and can get cash from government contractors typically barred by pay-to-play rules. Gov. Jon Corzine’s political team established one called Save Our State to promote his ill-fated toll-road monetization plan. After a delay at the start, it began announcing its donors on a monthly basis. Reform Jersey Now — which has strong ties to Christie’s political advisers — says it will reveal contributors on a schedule to be determined later.

The bill would apply to any issue organization attempting to influence an election or providing political information about candidates or public questions that raise or spend at least $2,100. Its donations would have to be reported to the state Election Law Enforcement Commission. If the bill were ever to be enacted, it would take effect roughly four months after that time.
